Also some antivirus/security and automatic backup programs will remove Restore Points. As
will some Registry Cleaners and System Optimizers (both of those are like Snake-Oil), and
of course some malware.

Hi, Rob,
I've now installed Shadowexplorer (I thought I already had Net Framework 3.5), but now have to work out what to do with it.
As regards possible Malware, I've repeatedly run the most recent definitions in Malwarebyte, Spybot Search and Destroy, Superantispyware and Malware fighter. Also Avast. All were negative each time
